[Discussion] Can't find account

Today I installed update.
I logged in with my main account: Claymorep
All ok
I swithed account to second one: Claymore2
...
Now I'm unable to swich account. I don't see the primary linked to google and I have the "link account" option on (even if the second account was linked to another google account too).

I tried to reinstall the game, but nothing,
I tried to create a new google account, but nothing
I wrote to igg but they answer to abilitate calls in settings... and clearly nothing

Can someone help me?
Every time I log in, I log in with secondary account without any option
